There is no denying the need for an air conditioner as the broiling heat of the summer sets in. The cooling industry is currently filled with a wide range of choices to choose from any time you simply choose to make your living or office comfortable. 

The portable air conditioner, not so much a conditioner as a transformer, is a cure to the summer pain from hot and humid air.  You should wheel it anywhere it is most powerful and points it in the direction that offers optimum relief since the air conditioner drives on small rolling wheels.

This makes it easier for you to put the cold air where you need it. When you think about it, it’s just cool. 

How Portable Air Conditioner Works


All types of air conditioners and even the fridge all operate much the same way. A portable air conditioner works by drawing hot air from the room into the unit. 

Next, the engine inside the portable AC cools the air in the room for ventilation. The portable air conditioner often takes the warm air and excess humidity and forces it out of the window and into a hose.

A portable air conditioner’s primary function is to remove the heat from a room and send the heat outside.

As for portable air conditioners, the cool and dehumidified air is carried to space by air flowing over the cold end of the coil. Since moisture vapor suspended in the air condenses as it reaches the cold coil surface, the air is dehumidified. 

The moisture drips from the coil and gathers in a pan, runs to a drain downward, or is being used to cool the coil’s hot portion. Meanwhile, air flowing over the coil’s hot end discharges into a hose running to the outside.

Choosing the Best Portable AC

Each type of device comes with capacity, energy usage, and cost trade-offs, so choosing the best one for you involves thinking about the size of your room, whether a permanent system is or can be set up for your house, and your cooling needs. 

Here are the best portable air conditioners that can keep you comfortable and make it easier to have versatile mobility.

#5 BEST OVERALL FEATURES: Whynter Elite ARC-122DS Portable Air Conditioner


This Whynter Elite ARC-122DS portable air conditioner has received an impressive amount of favorable feedback from consumers. It seems like any portable AC you’d find online at first sight, and that’s true in most cases, but that doesn’t actually mean that it’s not worth considering. 

Perhaps the Elite ARC-122DS might be the perfect option if your home doesn’t have a central cooling system and you need something to take with you easily from room to room.

Exhaust Hose

Compared to many portable air conditioner units, the Whynter Elite ARC-122DS has one distinct benefit. While most have an exhaust hose that blows the hot air out of the room, a second hose is provided to bring in air from outside. 

While this may not sound like a big advantage over the use of air from within the room, it makes it more effective.

If needed, the Whynter Elite ARC-122DS can also work with only one hose, but it will be less effective. It is designed for cooling rooms of up to 400 square feet and has three fan speeds, auto evaporation and modes of dehumidification and fan only.

Maximum Cooling Capacity


In rooms up to 400 square feet, the 12,000-BTU ARC-122DS is designed to decrease the temperature. This is not the largest portable AC that you can find by far, but this is more than enough power that you may need for the typical bedroom, kitchen, media space, and home office unit.

Two-Stage Filtration

A dual-stage filtration system consisting of a washable pre-filter and an activated carbon filter is used in the ARC-122DS. The pre-filter helps to capture and avoid large particles from entering your home from outside. These filters aren’t the most sophisticated, but they perform just fine as per portable air conditioner standards.

Programmable Timer

The ARC-122DS has a programmable 24-hour timer that can be arranged after a few hours of use to switch on at a certain time or turn off.

Before you walk in, your house will be as cool as a cucumber, and it also saves electricity by going off automatically when you don’t need it.

#7 BEST FOR LARGE AREA: De’Longhi Pinguino Deluxe Portable Air Conditioner


De’Longhi has a strong credibility for producing and manufacturing outstanding small kitchen appliances and HVAC systems. One of them is the De’Longhi Pinguino Deluxe 3-in-1 Portable Air Conditioner.

The new Pinguino is able to cool extra-large rooms and connected rooms with a total area of 600 to 700 square feet to as low as 60 degrees Fahrenheit in terms of versatility.

Although cooling is, predictably, the main feature of the unit, it is differentiated by its secondary functions from other versions in the De’Longhi line—as well as from other manufacturers.


This Pinguino model is capable of dehumidification, and it also holds mold and mildew growth at bay with its Bio Silver Filter. Although you can’t adjust it to a fixed level of humidity, the device constantly collects humidity on its own from the air.

Quiet Mode


The Pinguino relies heavily on low-noise handling. To trigger the Quiet Mode, simply push the button, either on the remote or the control panel. This upgraded device only runs at half its predecessor’s volume—and its fan mode is much quieter.

Fan mode

There is also a stand-alone fan configuration, even when heating or cooling modes are not in operation, to improve air circulation. It also functions with significantly less noise than any of these modes and can run at varying speeds.

Product Specifications:

  • Dimensions (l x w x h): 18.3 x 34.3 x 20.1 inches
  • Product Weight: 83.33 lbs
  • Rated voltage/Frequency: 115 (V~Hz)
  • Color: Black
  • Dehumidifying Function: Yes
  • Fan speed: 3
  • Recommended Room Size: 700 sq. ft.
  • Cooling Capacity:  14000 BTU (ASHRAE)/ 8600 (DOE)
  • Input Power: 50 Watts
  • Fan Function: Yes
  • Remote Control: Yes


  • With its advanced technological features the Pinguino is certainly capable of cooling as well as overall temperature control. In a remarkably small period of time, the device is also good at cooling confined spaces.
  • Although dehumidification is a secondary function, its output presents the device as a cut above portable air conditioners that are similarly priced — especially those without this feature.
  • Odor elimination is another advantage of dehumidifying, and is especially appealing if you intend to set up the Pinguino air conditioner near your kitchen.
  • The Pinguino 3-in-1 is bundled with adaptable attachments to fit your window, like other units in the De’Longhi range of portable air conditioners. For easy storage it also comes with an end-of-season cover.


  • Although a portable unit is indeed the Pinguino 3-in-1, it weighs in at a staggering 70 pounds. It’s simply not built to go up and down stairs with ease, regardless of being on caster wheels and having convenient handles.

The Ultimate Buyer’s Guide: Best Portable Air Conditioner 

Portable air conditioners are not only a smart choice, they are also a perfect way to save money and cut the amount of electricity you consume. In fact, the advantages associated with these AC units are numerous.

Whatever the reason to start considering a portable air conditioner, before making a purchase, it’s important to find the right portable AC for your room.

Here are the key things you need to know to help you make an informed decision in your AC search, to help you find the right portable air conditioning unit for your home and lifestyle.

Product & Room Size


Even if you decide to maintain it for the long run in one place, you need to ensure it fits in that spot. Measure the space to make sure that the dimensions of the package meet what you have room for. 

Decide whether you’re going to need to rearrange the space for it to fit in the position you’ve picked and whether or not you’re all right with that.

Energy Consumption


If it is necessary for you to save on energy bills, you can also give preference to finding an air conditioning unit with a programmable thermostat that will automatically turn off when your room hits the temperature you have set it for. 

Make sure you keep your machine clean and well run, since more electricity would end up being consumed by any AC that needs to do more work due to poor maintenance.

Noise Level

If having an AC device that doesn’t bring too much noise to your home when it’s switched on is vital to you, you will find some that are built to be quieter than normal. If manufacturers have put work into making an air conditioner louder, you can bet that in their specifications they would note that.

Yet, essentially, reading consumer feedback is one of the best sources for learning what to expect from the noise of an air conditioner. If you see reports about the noisiness of the AC, then you know that it’s not for you.

Simplicity of Use

It would usually be pretty easy to use most of the portable air conditioners, but you have a few things to remember that will affect how much work they take.


An air conditioner that comes with a dehumidifier can assist in removing air humidity. For many reasons, regulating the humidity in your home is beneficial as the heat begins to rise.

Heater Feature

An air conditioner that serves as a heater will save you the difficulty of having to buy a separate product in the winter to keep your home warm. As you can use it year-round, this feature will give you more value for money.

To Sum Things Up

Summer doesn’t need to have a downside, at least not when, on your own terms, you can regulate the heat in your home. 

When it comes to buying a portable air conditioner, there’s a lot to consider, and the first time you switch it on during a sweaty summer day, you’ll be glad you’ve taken the time to read this the best portable air conditioner.
